FOR THE STUFFING: Heat oil in a pan on medium - high heat and add onions. Add salt and let the onions caramelize well, stirring occasionally taking care that the onions doesn't burn turning the heat down as required. Once caramelized add turmeric powder + garam masala + chilly powder, sauté and add tomatoes.

Saute well till the water content evaporates, add sliced boiled eggs, mix and keep the mixture aside to cool.

FOR THE STRUDEL: Open the pastry sheet and thaw it on a lightly floured parchment paper or baking sheet for 40 minutes or as per instructions. Leave the space in the center, top and bottom and cut 1 inch strips at a 45 degree angle along the sides. Once thawed, brush lightly with melted butter.

Place the filling in the center of the sheet leaving space on the top, bottom and sides of the sheet. Fold the top on the sheet, then the strips alternating on each side creating an overlapping braided pattern.

Brush the strudel with egg wash and sprinkle with sesame seeds.

Bake in a preheated 400 degrees Fahrenheit or 205 degrees Celsius oven for 25-30 minutes or till the top is dark golden brown.
